Chapter 4 - Smart-Frame Protocol CARROLL TOUCH
4-4 Touch System Programmer’s Guide
Scan reports present interrupt beam data with no software interpretation
and are used for diagnostic and testing purposes. Coordinate reports
present interrupt beam data in the form of x, y (x-axis, y-axis)
coordinate pairs for application processing.
Touch Mode Commands
Touch mode commands select the conditions under which touch
coordinates are reported when the reporting method is set to coordinate
reporting. Touch mode commands are shown in Table 4-3.
*Add Exit Point is a modifier that is used with other touch modes. It is not a stand-alone touch
mode.
To change the touch mode, simply send the touch mode command that
selects the new touch mode. For example, to change from Enter Point
Mode to Tracking Mode, send the Tracking_Mode (26H) command.
